1. What is Decimal ASCII Conversion?

Decimal ASCII conversion translates each character in a word or text into its corresponding decimal ASCII code. ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric values to letters, digits, and symbols.

2. How Does the Calculator Work?

The calculator converts each character to its decimal ASCII value:

Example:

• 'A' → 65
• 'B' → 66
• 'a' → 97
• '1' → 49
• '!' → 33

3. Importance of ASCII Conversion

Details: ASCII conversion is fundamental in computer programming, data transmission, and character encoding. It allows computers to represent and process text data numerically, enabling various text processing operations and communications between different systems.

4. Using the Calculator

Tips: Enter any word or text in the input field. The calculator will convert each character to its decimal ASCII value and display the results as space-separated numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of ASCII decimal values?
A: Standard ASCII uses values from 0 to 127, while extended ASCII goes up to 255. Control characters occupy 0-31, printable characters 32-126, and extended characters 128-255.

Q2: Does this work with non-English characters?
A: Basic ASCII covers English characters. For non-English characters, UTF-8 encoding is typically used, which may produce multiple decimal values for a single character.

Q3: What's the difference between decimal and hexadecimal ASCII?
A: Decimal uses base-10 numbers (0-9), while hexadecimal uses base-16 (0-9, A-F). Both represent the same underlying binary data but in different numbering systems.

Q4: Can I convert decimal back to text?
A: Yes, using the chr() function in PHP or equivalent functions in other programming languages, you can convert decimal values back to their corresponding characters.

Q5: Why are uppercase and lowercase letters different values?
A: In ASCII, uppercase letters (A-Z) range from 65-90, while lowercase letters (a-z) range from 97-122. This 32-value difference allows for case conversion through simple arithmetic operations.
